Eight Chinese police officers will go on patrol in Italy in early June to help their Italian counterparts protect Chinese tourists, a senior police official said on Monday.

The officers, selected nationwide and proficient in Italian, will patrol scenic spots in Rome, Milan, Florence and Naples to help deter crimes against Chinese tourists, said Liao Jinrong, director of the Ministry of Public Security's International Cooperation Bureau.

The patrol duties will last for two weeks or possibly longer, depending on the needs, Liao said. The Chinese officers may not be armed, and they have no law enforcement authority on these patrols, he said.

China may also send police officers to Austria and Spain later this year to help ensure Chinese tourists' safety and to aid in communication, Liao said.

"Joint police patrols are an effective means of expanding mutual trust and giving tourists a stronger sense of security," he said. "They can also help us better understand each other's legal systems and police procedures."

China and Italy signed a memorandum of understanding on joint police patrols in September 2015, the first such agreement between China and a European country. A first group of four Chinese police officers patrolled in Rome and Milan from May 2 to 13 last year.

Four Italian police officers began patrolling in Beijing and Shanghai on Monday and will continue to May 7.

They may not carry weapons, but can offer advice and help handle cases targeting Italian tourists in tourist spots, according to China's Ministry of Public Security.

Ettore Francesco Sequi, Italian ambassador to China, said on Monday that Italy has supported and praised the joint patrols, which will "play a significant role in promoting bilateral safety cooperation and fighting cross-border crime".

Pang Bo, a Chinese policeman who patrolled in Italy last year, said two Chinese police officers wearing Chinese uniforms patrolled with two Italian officers usually from 8:30 am to 4:30 pm.

They were generally deployed in tourists sites, railway stations or other places where Chinese might gather. Their main task was to answer Chinese tourists' questions and help them communicate with Italian officers, Pang told Chinese media last year.

Gao Yunbin, a Ministry of Public Security media officer, said Chinese officers would "rush to the scene to assist their foreign counterparts" in cases involving Chinese tourists.

As the number of Chinese tourists in Europe has grown in recent years, so have the crimes against them.

Liu Jianming of the China National Tourism Administration said on Monday that more than 800,000 Chinese and Italian tourists visited each other's nations in 2016.
